Back to: Blockchain 101 by EOS Union- 什么是区块链？
由于区块链没有一个中心化代理来指挥、协调，又要保证每个节点数据的一致性，所以区块链需要一个机制，这个机制需要解决两个基本问题：
Since the blockchain does not have a centralized agent to command and coordinate, the blockchain needs a system to ensure the consistency of data of each node,. This system needs to solve two basic problems:
1.这么多人（节点）中谁有权记录数据——一次只有一个人可以记录；
- Who has the right to record data in so many people (nodes) – only one person can record at a time;
2.其他人（节点）如何同步数据——因为要保持数据的一致性。
- How other people (nodes) synchronize data – because data consistency is maintained.
